It is to be understood that changes may be made in the constructionV and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims. Y

What I claim is 1. An unloading device of the class de- V scribed, comprising a casing-1y having its top and one end open, a roller journaledin each end of the casing, intermediate rollers in the casing, shafts for the same and on which Ythe rollers are loosely mounted,ran endless belt piSSng over the rollers shields at the sides of the casing and having channel shaped lower edges for receiving the edges of the belt and adjustable gates in the top ofthe easing for controlling the flow of material onto the belt., f

`2. An unloading device of the class described, comprising a casing having its 'top and one lend open a roller journaled in each end of the casing, intermediate rollers in the casing, shafts for the same and on which the rollers are loosely mounted, each inter-V mediate roller being of spool shape with its ends separate fromthe center, an endless belt passing over the rollers, shields at the sides of; the casing and having channel shaped lovverV edges for receiving the edges of the v belt and'adjustable gates in the top. of the casing for controlling the flow of material vonto the belt.

8.V An unloading device ofthe class de'- scribed, comprising a casing havingits top and one end open, a roller journaled in each end of the casing, intermediate rollers in the casing, shafts for the same and on which the rollers are loosely mounted, an endless belt passing over the rollers, shields. at the sides of the `casing and having channeles'haped loWeredges for receiving the edges of the belt, adjustable gates in the top of the casing for Vcontrolling the flow of material onto the belt, each gate extending longitudinally of the casing and having channels in its under; facebell cranks on. each side of the casing and having rollers thereon engaging the channels and rods for moving the bell .cranks to openand Close the gates.V i Y In testimony whereof I aiix my signature.
